[Idiopathic hepatic angiosarcoma. A case report].

Hepatic angiosarcoma is a malignant mesenchymal neoplasm of endothelial cells of high grade. Hepatic angiosarcoma represents two percent of all primary neoplasm liver. The highest incidence is between the sixth and seventh decade of life, youth and children is rare, predominantly in men (3:1). Most are idiopathic (75 %). Diagnosis is difficult because clinical manifestations and imaging studies are inconclusive. When clinical manifestations begin progression is often fast, and possibilities for curative treatment are limited. We report the case of a man aged 17, presented two clinical episodes of hemoperitoneum with ultrasound and CT diagnosis of hepatic hemangioma, hepatectomy was performed in the right lobe, the histological study reported multicenter liver angiosarcoma.
